Answer:
x=9
Step-by-step explanation:
−4(4−x)=4/5(x+16)
(−4)(4)+(−4)(−x)=(4/5)(x)+(4/5)(16)(Distribute)
−16+4x=4/5x+64/5
4x−16=4/5x+64/5
4x−16−4/5x=4/5x+64/5−4/5x
16/5x−16=64/5
16/5x−16+16=64/5+16
16/5x=144/5
(5/16)*(16/5x)=(5/16)*(144/5)
x=9
hopfully this helps answer: x=9
X=3 y=5 hope this helped :)
$68 net price
$.02 x 4000 units= $80
$80 x 15% (discount) = $12 discount
$80- $12 = $68 net price
B. (-2,2)
The solution is where the two lines intersect
Since they give you the graph find the highest point in the curved line:
the line touches the number 100
so it's maximum height is 100 feet
now from where it touches 100 look at the time:
it hits 100 feet at 2.5 seconds
